Synchronisation in cortico-cortical network of the human brain

The human brain controls many body functions, manages our thoughts, memory, speech, movement and all the organs of our body. It is estimated that the human brain contains about 10^11 neurons, where each neuron is connected to approximately 10^4 other neurons. The occurrence of synchronisation in some specific areas of the brain may be associated with abnormal pathological rhythms, correlated with neural diseases such as movement disorder (Parkinson's disease, epileptic seizure, lesions). On the other hand, it is also responsible for some vital brain functions, such as processing of sensory information and motor function. With this in mind, we will present a network topology according to the cortico-cortical connection network of the human brain and verify the existence of spike and burst synchronisation in different cortical areas. Our simulations show that the network used in this work has a rich-club organisation and plays an important role in the transition of the areas from desynchronous to synchronous behaviours.
